To all whom it may concern:

Be it known that we, ELLsWoRTH E. HAIN- LINE and EVERETT C. OULP, citizens of the United States, residing at Kansas City in the county of Wyandotte and State of ansas, have invented a certain new and useful Improvement in Sash Fasteners, of which.

the following is a specification. I

Our invention relates to improvements in sashlocks.

The object of ourinvention is to provide a novel sash fastener which is simple in construction, cheap to make, durable, not

liable to get out of. order and which may bereadily applied to windows now in use.

Our invention provides further a novel sash fastener which will hold the lower sash from upward movement and the upper sash from downward movement, when the sashes are in either the open or closed position.

Our invention provides further novel gravity actuated locking means which will automatically operate to lock the sashes together and to the frame.

The novel features of our invention are hereinafter fully described and claimed.

In the accompanying drawing which illustrates the preferred embodiment of our invention,

Fig. 1 is a horizontal sectional view of a portion of a window provided with our improvement.

Fig. 2 is a perspective view of our improved sash fastener.

Fig. 3 is a vertical section on the line 33 v of Fig. 1.

Fig. 4 is a vertical section view on the line 44 of Fig. 1.

Similar reference characters designate similar parts in the different views 1 designates the window frame in which are vertically slidably mounted in the usual manner an upper sash 2 and a lower sash 3.

4 designates a supporting member arranged to be attached by screws 5 to the upper end of the lower sash3.

6 and 7 designates respectively two locking members, preferably, as shown, in the form of two wedges, the sharpened ends of which are respectively adapted to penetrate and lockingly engage the frame 1 and the adjacent stile 2.

The locking member 6 is pivoted by a transverse horizontal pin 8 to and between two upwardly extending flanges 9. on the upper side of the supporting member 4.

The'locking member 7 isadapted to be pivoted bya in 10 disposedjat right angles horizontally to the pin 8." The pin lO'is adapted to be mounted in either oftwo sets of holes 11 and '12. disposed parallel with each other at right anglestothe pin Sin two upwardly extending flanges13 on the upper side of the member't and which are disposed at right angles to the flanges 9. When the supporting member 4: is to be mounted at the left side of a window, as shown in the drawing, in Fig. 1, the pivot pinlO is mounted in the holes 11. When the fasteneris to be mounted at the right side ofthe window, the

pin 10 is mounted in the holes 12.

In the operation of our invention, the wedge members 6 and 7 are swung to the upwardly inclined position shown, in the drawing, in which position downward movement of the upper sash 2- will cause the wedge 7 to penetrate and lockingly engage the sash and prevent such downward movement, while permitting the sash to move upwardly.

The upward movement of the lower sash 3 will cause the wedge 6 to penetrate and lockingly engage the frame 1, thus preventmg the upward movement of the lower sash while permitting it to move downwardly.

When the fastener is to be used at the right side of a window, the pin 10 is mounted in the holes 12 and the wedge 7 is swung thereon to the inclined position shown in dotted lines in Fig. 3.

To retain the fastener in the unlocked position, the wedge members 6 and ,7 may be swung from the locking position past the vertical planes which intersect the pins 8 and 10 respectively. It will be noted that the position of the plate 4: on. the lower sash is such that the wedges 6 and 7 will, when engaging the frame and upper sash respectively, be at a relatively flat inclination, whereby when the lower sash is raised or the upper sash is lowered, the wedges'will be easily forced intothe wood. Continued upward movement of the lower sash or con-' than width in order to withstand great pressure a plied to the wedge 6. Such length of base requires the member 4: to be disposed lengthwise on the upper rail of the lower sash. Owing to the requirement of this disposition of the base on the upper rail, the base is provided with the two holes to receive the pivot pin 10 in the two ivotal positions of the wedge 7 Thus when the lock is used at either the right or left side of the window, the base plate 4. is disposed longitudinally on the upper rail of the lower sash, so that in either position, the base plate will be securely anchored to the sash. As shown in Figs. 1 and 3, the base plate l and flanges 13 extend across the joint between the upper and lower sashes, so that when the member 7 is in the locking position, the base plateand the flangesl3 prevent access from the outside through'the crack between the sashes to the locking member 7 for the purpose of f elo'niously releasing it.

h We do not limit our invention to the structure shown and described, as many modifications, within the scope of the appended claim may be made without departing from the spirit of our invention.

What we claim is.

In a sash fastener, a supporting member adapted tovbe attached to the upper side of the upper rail of a sash and having two horizontal parallel holes spaced apart from each other at equal distances from the bottom of the supporting member, a pivot pin adapted to be inserted in either of said holes, and a sharpened wedge arranged to be mounted on said pin, and adapted to penetrate and lockingly engage a frame in which the sash is mounted, the wedge being adapted to be swung on the pin so as to bear upon the upper side of the supporting member,

substantially as set forth. In testimony whereof we have signed our names to this specification. a
